Fair enough.  Note, however, that as someone pointed out,
it's actually the *fourth* of something, and it would not
necessarily be a byte.  In fact, in your case, it's not:

This defines an array of *3* long (32-bit) integers.

Each of these is just indexing into that array, starting
as Python does with an index origin of zero.

Between the clarifications you've got and Duncan's post,
you shouldn't have much more trouble now. :-)
